您要查找的是不是：
- For distributions in several variables, singular supports allow one to define wave front sets and understand Huygens' principle in terms of mathematical analysis. 對于多變量的分布，奇支集也可以更精確地被描述為，從而可以利用數學(xué)分析來(lái)理解惠更斯原理。
- The news from the front set him in the twitters. 前方來(lái)的這則消息使他緊張不安。
- At each interface the spreading wave front is made discontinuous. 在每一分界面上擴展的波前出現間斷。
- It starts with zero and grows to a maximum slightly behind the wave front. 它從零值開(kāi)始，并在稍后于波陣面處增長(cháng)到最大值。
- Just like in the roving step, the front set of rollers rotates faster than the back one. 與粗紗工序相似,前羅拉的轉速高于后羅拉的轉速。
- The radii are proportional to the time which has elapsed since the wave front occupied the position wi. 半徑與波前占據wi位置以來(lái)能經(jīng)過(guò)的時(shí)間成正比。
- This assumption is reasonably justified in the early stages, when the wave front is not far from ground zero. 這種假定在初期階段波陣面離地面零點(diǎn)不遠時(shí)是相當合理的。
- In spinning,the front set rotates about30 times faster than the back set. This difference in steed attenuates the yarn and makes it even, smooth and uniform. 一般前面一對羅拉的轉速是后面一對羅拉的30倍,這樣速度的差使紗條抽長(cháng)拉細,變均勻,變光滑。
- If a refraction or a reflecting body is irreqular, the wave front undergoes a deformation. 如果折射體或反射體是不規則的，波前即產(chǎn)生變形。

- Successive wave fronts in this case form a series of concentric spheres. 相繼波前形成了一系列的同心球面。
- Coming in a handy reusable container, the front set contains 6 various springs while the rear set has 7, making for a cost effective way to obtain all possible spring combos. 未來(lái)在一個(gè)輕便的可重復使用的容器，前六集包含各種溫泉的同時(shí)，后方載有7名，使一個(gè)符合成本效益的方法以取得一切可能的彈簧組合。
- The planes of the wave front and the reflecting surface are also normal to the plane of the figure. 波陣面的諸平面與反射面都與圖面垂直。
- If a refraction or a reflecting body is irregular, the wave front undergoes a deformation. 如果折射體或反射體是不規則的,波前即產(chǎn)生變形。
- When the incident wave front reaches this point, the reflected wave is still some distance away. 當入射沖擊波波陣面到達這一點(diǎn),反射波離開(kāi)它還有一段距離。
- High-pressure acting on samples were produced by shock wave front converging in metallic ball. 在該裝置上 ,利用沖擊波由金屬球體表面向中心匯聚形成的高壓 ,對樣品進(jìn)行了沖擊處理 ;
- All elements are radiating in phase, and the resultant wave front is perpendicular to the axis of the element array. 所有單元發(fā)射相位一致，合成的波前垂直于單元陣列軸線(xiàn)。
- Such wave fronts are seperated from one another by one-half wavelength. 這種波陣面彼此間隔半個(gè)波長(cháng)。
- Radiation from air shock wave front produced by explosion is an excellent microsecond illuminant. 炸藥爆炸產(chǎn)生的空氣沖擊波陣面的輻射是高速攝影中的一種良好的微秒級持續時(shí)間的照明光源。
- Such wave fronts are separated from one another by one-half wavelength. 這種波陣面彼此間隔半個(gè)波長(cháng)。
